The'inachine embodies a; suit-hie frame '1' inwhlch there is mou tedior'verticalislid 111g movement,' a carrier" or shaft 2 for the handle or article tofbe operated 011;" said carrier heing providedfat' its" lower end with a a. forwardly extending yoke 3 havingat its forward end an upstanding standardegy The carrier 2 is provided With a forwardly projecting'spur 5; While a spurt is slidable' wlthinthe standard 4': in'alinenlen't With the spur 5,'said spurs or grippin'g elements' be ing adapted to bit'e'the opposite endsof' the grip portion of the blank hai'idle 7 with the shank 8 of said handle projecting up? Wardly and centerdloy a forwardly pro jectingfork 9 into Whichthe shank-ismoved when applied to the machine;

In order to force the spur or rod 6 rear wardly to grip and'holdthe handle between the spurs, arr-upwardly projecting lever 10 has its lower end pivoted; as at'll, to the standard 4, and said lever projects 'up Wardly across the'for'w'ar'd end of the spur 6 and carriesan adjusting scre'i'v '12 adapted to abut against tlie'i oi'ivard heel end of the spur 6 when the lever 10 is swung rear- Wardly, so as to force the spur rearWa-rdlv against the handle. A suitable--spring'cateh Patented Apr-t9, i918;

12 is carried by the upper end of the-stand ard 4 to snap into engagement ith thelever 10 and hold it When said lever is forced rearwardly to project the spur 6into 'en gagement with the handle, thereby retaining' the spur 6 in gripping positiomsothat the handle-Will be firmly held Within the carrier; By releasing the catch 12, either manually or mechanically, this Will release the lever 10 and spur 6, enabling the hair dleto be removed. I V I Theca-rrier 2 is elevatedafter the outer side ofthehandle grip is finished, for other operations not forming 'a' part ofthe' present invention'l Thus, a suitable cam 13 is mounted loosely" upon a transverse sh'aft'lfl journaled tothe'fram'e below the standard 4 and said oain is under the yoke 3501' raising the carrier at the proper time, The

shaft 14: rotates. continuously during the operation of the machine, andia earn 0011- trolled clutch is employed for connecting the cam '13 with the-shaft at the proper moment to give said cam a complete rotation.

rier2 is raised by with the arm 23 of a rock shaft 24 carried by the frame and having another arm 25 engaged at the proper 26 carried by a cam disk 27 secured upon a longitudinal shaft 28 geared, as at 29, with the drive shaft 20, the shaft 28 being rotated at a much-slower speed than the shaft 20. The shaft 28 makes one complete rotation for each cycle of operation. The carrier. 2 has rearwardly ex tending lugs 30 engageable with cam flanges 31 projecting from the forward face of the cam disk 27 whereby. after the carthe cam 13, the forward ends of the flanges 31 engage said lugs, thus moving the carrier downwardly to return it to its starting position, during which returning movement of the handle with the carrier, the handle can be operated on by other finishing means (not shown). When the cam 26 contacts with the arm outwardly, the link 22 is pushed by the arm 23 to swing the lever 21 and bring the clutch member 16 into engagement with the clutch hub 15 and holdingit so engaged, whereby the cam 13 completes one revolution, the arm 25 then being released, so that a spring 21 then returns the parts to normal position and disengages the clutch member 16 from the clutch hub 15 with the cam 13 in normal idle position, the carrier 2 having been raised and then supported by the cam flanges 31.

Coming to the improved finishing mechanism for the outer side of the handle grip, the same embodies a guide 32'having the par allel vertical longitudinal side plates 33 connected at their rear ends by the end wall 34 provided with an upper recess 35 for receiving the spur 5 when the carrier 2 is lowered for starting position. A U-shaped abutment 36 is secured to the wall 34 in register with the recess 35 to accommodate the spur, and adapted for the abutment thereagainst of the rear end of the handle grip when the handle is placed into the machine. The guide 32 is seated upon a shelf 37 with which the frame is provided, and can be seinged thereon by means of bolts 38 or the Carried by the guide 32 is a device for temporarily holding and positioning the handle when introduced, said means emmoment by a cam 25, and swings it.

the ends of j having a transverse T-head' atits lower end providing the outwardly and inwardly extending finger 44 and 45, respectively. The finger 44 is intended for engagementwith a depending catch or detent 46 pivoted at its;

upper end, as at 47, to one'side plate 33, and

provided near its lower end with a rounded lug 48 for the engagement of the finger 4.4 when the arm 39 is raised to handle-supporting position, as seen in Fig. 1., The catch 46-is 'yieldably held in position by means of a spring 49 connected thereto and to the frame, so raised into active position, the finger 44 will snap into engagement with the lug 48, thus holding the arm 39 raised, but enabling said arm to be forcibly swung downwardly, for which purpose said arm has an upwardly extending finger 50. The arm 39 is raised by the contact of the yoke 3 with the finger 45 when the carrier is raised to uppermost position, thereby placing the arm 39 in holding position when the carrier has been raised, in which position the arm 39 will remain as the carrier is lowered, so as to be in place for receiving and positioning the next handle. 1 7

The cutter for trimming the outer side of the handle grip is carried by an arcuate slide 51 having the side plates 52, said. slide mounted for curvilinear sliding movement within the guide 32, and the side plates of said slide and guide having interengaging curved tongues and grooves 53 for guiding the slide for movement in the desired arc to trim the handle grip with a longitudinal curvature. The cutter 55 is curved and suspended within the rear end of the slide 51, the cutter having outstanding lugs-54 overhanging the side plates 52. The lugs 54 are clamped on the plates 52 by bolts 56 extending through slots 56 in the lugs and the lugs seat on adjusting studs 56 which can be adjusted to adjust the position of the cutter relatively to the slide 51 in connection with the adjusting screws 56 and bearing against the front edges of said lugs carried by the plates 52.v Said cutter curved transversely of the slide and is of concaved form in edge view, one edge of the cutter being sharpened to shave the corners of the handle grip OK. A yoke 57 connects the plates 52 near the cutter to render them rigid against the shoulders or lugs 54. The cutter 55 is curved to give the that when the arm 39 is handle grip the desired transverse curval3 ture. The standard 4: projects upwardly within the cutter slide 51, saidsl-idebeing.

slotted sothere is no interferencebetween the movement of the standard t and slide 51, the slide 51 beingnormally moved for vardly to retracted position. with the cutter 55 immediately in rear of the standard 4 Y belowthe spur 6.

.The actuatingmechanism:for the slide 51 embodies-a Usshaped' link 58-hav-ing1its-terminals pivoted to the plate 52 within-the forwarden'd of-the slide51, so that said link can" move astride the-lever 10 and standard 4 when moved rearwardly with the slide 51, there being a longitudinal slot betweenthe sideportions or the slide andl-ink-extending to the remote ends thereof for accommodating'th'e standard. 4 and-lever 10 which project upwardly through said slot. The closed forward end of the link 58 ispivoted to an upstanding arm 60. secured to a transverse rock shaft 61 carried by thev forward portion of the-"frame and provided'witlra downwardly projecting arm 62 fastened thereto, while an arm 63 'is-' mounted loosely on the roclc shaft 61 adjacent to thevarmr62 and has lugs or ears- 64; to move astri'de the arm 62, thereby providing a clutch for connecting the arm 63 and arm 62. A lever 65 fulcrumed to the: frame at one side between its ends has one arm engaging a groove 66 of the hub of the arm 63, and a pushrod 67 is connected to the other-"arm of the :lever 65 and is slidab'ly carried by the frame, being 'VVhen the cam 69 engages" the roller 68, this pushes the rod' 67 and. swings" the lever 65 to move the arm 63 into engagement with the arm- 62' toswing't'he'latter with the arm 63. The arm 63 is continuously oscillated during the operation of themachiner-and 'for'this purpose a gear wheel73 meshing with a geanwheel 74 secured upon the drive shaft 20, is connected by a connecting rod '75 with the arm 63; Vhen: the cam"69 engages the roller 68 it moves the arm 63 into:engagement witlr the arm 62-wheni'in rearwardly swung position, and the cam 68holds the arm 63 in engagement with the arm: 62 until they have been moved" forwardly and: then rearwardly, at which: time the "arm 63 is released from' the arm 62 by the spr-ing'70 connectedto-the lever 65,. the cam 69 having 55 moved past the roller 68; lTlluS,"z the forward and rearward movement of thearm 62 with the arm 63,.will swing .the arm-60 rearwardly and then forwardly, thereby advancing thecutter slide 5lrfor the cutting operation and retracting it.

'lllhenathe CUttBPSllCle 1s advanced-to trim the handlegrip, the lever 10 is pushed rearwardly. to grip the handle 7 between the spurs and 6,"th1s being?accomplished-1by an upstanding lug 71 carried by the closed end of th-e link 58andhavinglan adjustable screw 7 2 to contactwithjtheupp'erterlfi n of the. lever .10 and niovedreai'wardl'y when the slide 51 is completing its rearward movement.

The operation of the .mechanism is as follows: Normally, the. slide 51 is retarded forwardly. the lever. 10' swungjforw'a'rdly and theqspur 6 moved forwardly slightly, the cam r13 in the pe'sitionseen in7Eig. 1", and-the handle-holding.arm 39 in raised position, being held bythe catch 46. The operator then introduces the handle 7 ,placing. the same in a vertical longitudinal. plane with the rear portiontof the handle grip seated on the seat 42-against the portion .41 of t-he arm ---39and in abutment :with the ab.utment;36,-the shank 8 being placed in. the fork 9; This will hold the handle in proper position, --and the 'finger 50 of .the arm -39 will project upwardly in the path ofoneside plate 52 ottheslide 51. Theoperator then starts the machine by throwing in a; clutch (not shownlto start the: rotation of thedrive shaft-20, as willbe readily understoodland the cam 69 in engaging the rollerj 68 wi-ll move the arm 63 intoyengagement with the arm 62, thereby swingingsaid a-rm62 forwardly then rearwardly. Therefore 'the arm 60 Wi-Il-first-be swung-rearwardly to move the link 58 and slide 51 .rearwardly,

ands the cutter 55-is, therefor rmovedlongitudinally along the handle grip underneath thesame from itsforward to itsrear end. The transverse curvature ofthecutter 55 with respect to tllG-Slld851WVJl'l. 1711111011 vthe corners of the handlegrip, and-the curvilinear movement of 'xthe slide 51 will give the handle grip the desired longitudinal curvature, the cutter 55 moving under "the abutment 36 in completing'wits movement, as seen in 4:. During the rearward movement of the-. slidet5l, its contact with the finger-5O tforces' the same rearwardly, thereby 'forcingthe arm 1 10 39 downwardly, and releasingv it from the catch-;t6,so that said arm 39 willdrop downwardly' out of the way, thus removingthe portion 41 and seat i 'from the handle so as not to interfere with thE/JHQYGDIQHE of the cutter and slide. The arm- 39, howeven serves: tohold the handle in' place until the cutter 55 has started its cutting action on the handle, the pressure-of the cutter against the handle forcing it'rearward'ly against'the 1 20 abutment 86 and-spur'5, so that thearm: 39

is no longer needed. WVhen theslide 51 com- .thehandle between the spurs 5 6,,the leverlObeing held by ther ca'tcl -JW. lThe handle v-is thus-gripped and. held; aspsoon as the cutter 55 completes its movement, the

elevate the handle with it. This upward movement of the carrier can be started during the return movement of the slide 51, since there will be no interference therebetween, and after thecarrier is raised, the lugs 30 thereof are engaged by the cam flanges 31, which will support and lower the carrier so that the handle can be operated on by other finishing means (not shown). Vhen the carrier is raised, the yoke 3 thereof in contacting with the finger 15 will'raise the arm 39 back into engagement with the catch 46, so that said arm will be in position to receive the next handle after the carrier 2 has been lowered to normal starting position and the completed handle removed by releasing the catch 12 from the lever 10, thus enabling the handle to be removed easily. When the carrier has been returned to normal lowered position, the cycle of operation is completed, and then repeated, as above described, after the finished handle is removed and a new blank handle inserted.

Having thus described the invention, what is claimed as new is:
